How to convert kilometers per hour to meters per second
Formula: m/s = km/h ÷ 3.6
Worked example: 100 km/h → 100 ÷ 3.6 = 27.7778 m/s
Multiply meters per second by 3.6, because an hour has 3,600 seconds and a kilometer 1,000 meters. A wind of 10 m/s blows at 36 km/h, and a sprinter at 10 m/s runs at 36 km/h.

What is a kilometer per hour?
The kilometer per hour is the speed unit on road signs and speedometers in most of the world, including Canada and Mexico. A highway limit of 100 km/h is about 62 mph, and 50 km/h, a common city limit, is about 31 mph.
What is a meter per second?
The meter per second is the SI unit of speed. Physicists, engineers and many weather services use it, especially for wind. A world-class sprinter averages a little over 10 m/s over 100 m, and 1 m/s equals 3.6 km/h or about 2.24 mph.
